CARCOUPLING.

SPECIFICATION forming part of Letters Patent No. 392,968, dated November13, 1888.

Application tiled April 19, 1888. Serial No.271,136. (No model.)

To aZZ whom it may concern:

Be it known that we, ANDREW JACKSON PICKARD and GEORGE MELsoN, citizensof the United States, residing at Eugene Oity, in the county of Lane andState of Oregon, have invented new and useful Improvements in CarCouplings, of which the followingis a specification.

Our invention relates to improvements in lo car-couplings; and itconsists in certain novel features, hereinafter described and claimed.

Figure l of the drawings is a side elevation of our improved coupling.Fig. 2 is a vertical longitudinal section ofthe same. Fig. 3 is i5aperspeetive View of the link detached. Fig.

4 isa perspective view of the link-follower detached.

Referring tothe drawings by letter,A designates the draw-bar of a car,and B the recessed zo draw-head attached thereto, which draw-head isprovided with the upper andlower couplingpin holes, b b', respectively,and the mouth b2, having the inwardlyconverging top, bottom, and sidesto direct the entering link. The recess b3 on the inner side ofthe mouthis rectangular. The link C has its ends c flattened on their outeredges,for a purpose hereinafter eX- plained. D is the couplingpin,having the rounded point d, as shown. E is the link-follower,rectangular in shape, and situated within the rectangular recess b3. Thesaid follower has the dat-bottomed transverse groove c in its front end,the vertical opening e at a proper point of its length,and the stem c2.projecting from its inner end. Fis a pin resting in the opening e andfalling by gravity When the follower ispushed in into the recess f inthe floor of the recess b3, which recess f has the inner inclined side,f, and the outer ver- 4o tical side or shoulder, f2, against which theouter side of the pin F abuts and retains the follower within thedraw-head against the action of the spiral spring G,Which surrounds thestem e2 of the follower, and the inner end of which bears against theend of the recess b3 or 45 against the block g, inserted therein.

It is evident that the spiral springs in the opposite draw-heads willpreventthe link having any loose motion.

The squared outer edge of the end of the 5o link rests in theflatbottomed groove in the outer end of the corresponding follower, thepressure of which, caused by the spring in rear thereof, holds the linkagainst the pin inside its bend and keeps it horizontal. 55

Before coupling, the point of the couplingpin rests on the top of thefollower, and when the latter is driven inward by the entering link thepin falls through the link and couples the draw-heads.

Having described our invention, We claim- The herein-describedcar-coupling, comprising the draw-head having a recess, f, in itsoor,provided with a vertical shoulder, f2, at its front end and With aninclined rear end, f', 65 the followerhaving a vertical opening, c',near its rear end and provided in its front end With the transverseflat-bottomed groove e, .the pin F,playing freely in the verticalopening e and having its lower end resting in the recessf, and thecoupling-link having at ends adapted to engage in the Hat-bottomedgroove c, substantially as specified.

In testimony that we claim the foregoing as our own We have hereto afxedoui-signatures in presence of two witnesses.
